$1$ Problem Description

During the distillation process, the input flow rate is $1000mo\frac{l}{h}$ containing $30\%$ ethanol, $40\%$

water, and $30\%$ ethylene glycol. There are three output streams: $1^{st}$ output stream contains $70\%$

ethanol and $30\%$ water; $2^{nd}$ output stream contains $20\%$ ethanol and $40\%$ water; $3^{rd}$ output stream

contains $5\%$ ethanol and $50\%$ water.

$($a$)$ Solve the material balance using both MatLab and Python

and calculate the flow rates for all three output streams.

$($b$)$ Draw the final and initial PFD with the flow rates labeled
